a wall having an .air space to insure against dampness passingzthroughfrom one side to the other, and also simple means for reinforcing withsteel rods and means for spacing the wallV to a uniform thickness.

Another object of my invention is to provide a simple and effectivemeans by the use of the projectingends of the wall bonds to act as ascreed, requiring certain thickness of interior or exterior plaster.

A further object of my improvement is to provide a continuous reenforcedcolumn of concrete functioning. as joist bearings, and means forstiffening the .wall vertically, also means for applying a horizontalreinforcing rod applicable to the wall construction in `general and moreespecially to reinforce a beam over openings in the wall, and withoutadditional forms.

Also means for placing metallic bonds when said wall is to be veneeredwith brick, stone, terra cotta, or other materials.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Fig. 1 is a fragmentary perspective view of a wallshowing corner construction, reinforcing and general assembly 0f theparts. Fig. 2 is a perspective view of one ol" the slabs. Fig. 3 is aperspective view of one of the bond blocks. Fig. et is a sectionaldetail view through bond block at the reinforcing rod, taken on line Ain Fig. 8.

Fig 2 shows one of the precast concrete slabs as employed in erectingthe longitudinal wall elements. The slab 1 is relatively thin in widthand of greater length than depth, the opposite corners along one edgebeing cut away as diclosed and the respective vertical end elementsthereof fashioned concave as seen at 3 and convex as seen at 6; thisleaves end elements on the other edge, longitudinally extending beyondthe end elements previously. mentioned which'are. like wise concave at 3andfconvex atl 6'but in'ref verse position to theother end elements 3and 6 of the slab. The-concave Sis-adapted to receive the convex .member4s of1 thefbond block and the concave 5 is adapted `to receive.

the'convex ends 6, by thismeans when the ends of slab 1 are' tightlyjambed' together.

with the bond blocks 7 interposedfbetween the ends of said slabslasshownin Fig. 5, will preventtheslab members" 1l from'spreading` durinthe course of construction. by

reason oft e -concave andconvex intermatching feature, and said bondblocksY being` inverted alternately'- will formr a; continuous.

head for the. formation of a columnas shown at 9in-fwhich-reinforcing;rods 10 willfloe placed and concrete poured asshown at 11',

which applies to all of the shafts yformed by the bond. blocks 7, andsaidconcrete will.

firmly unite the-members adjacent thereto.l D is anotchformedto-:receive axmetal'bond Ewithout separatingthe slabs 1` said bondsprotrude into the concrete. shafts 11: extend.- ing outward between thejointsA l?" of the veneered masonryVby' whichv means the veneeringis`firmlyv bondedxto t-he'wall'.`

ln Fig. 1 a portion of the wall is removed at which place is shown thebond block4 7 with the curved wing members down, and at C the bondbloclr is inverted, the object of which will be hereinafter explained.

The bond block 7 is molded of concrete, the center of which isrectangular in shape and has protruding members 12 the sides of whichare convex and concave as shown at l and 5, the height of the block 7cor-responds to the depth of the slab 1, while the height of each of theside members 12 beginning from the base of the said block 7 isequivalent to the depth of the cut away corner portions of the slab 1shown in Fig. 2, and by which medium the ends of slabs 1 are bondedtogether in parallel alinement, and in conjunction with said members thepro# truding square end 13 of said block functions as a separator forsaid slabs, and said members also contacts the opposite end of theadjacent bond block as they build up through the wall forming a verticalenclosure 9 as heretofore described.

The bond block 7 has semi-circular grooves 14; in each end of suicientsize for a reinforcing rod 15 to pass through without separating theblocks. '16 is a reinforcing rod` Aone more of which are inserted tostrenghtee the protruding members 12 by Which means slabs l are safelybonded together.

When said Walls are completed they may be plastered on the inside, andveneered With brick, stone, or other materials, or stuccoed on theexterior, and the application of stucco and interior plastering shall bein thickness equal to or greater than the protruding ends Gr of the bondblocks, said ends protrude past the surface of the Wall blocks 1 asshown by dottedline 23 in Fig. 4L.

' Modiiications may be made as lies Within the scope of appended claims.y

Having described my invention, I claim and desiie to secure by LettersPatent:

l. ln a Wall construction, the combination of a plurality of slabs,longitudinally extending, superposed in spaced vertical planes; theslabs in one vertical plane being arrange-d also in horizontal coursesWith a slab of like character immediately opposite it in the othervertical plane; each slab being greater in length than'the depth Withthe opposite corners along one edge removed; the slabs in a longitudinalcourse being alternately reversed in position, vertically and inabutting relationship along the longitudinal edges of their projectingend portions; and a plurality of bond blocks, superposed in alternatingreversed position and in spaced vertical planes7 transversely arrangedintermediate said longitudinal slabs; said blocks having a centralsection equivalent in Width to the spaced distance between the verticallongitudinal slab courses and With Wing portions outwardly projectingrtherefrom and arranged intermediate the adjacent ends of the contiguousslab members.

2. In a Wall construction, the combination of a plurality of slabs,longitudinally extending, superposed in spaced vertical planes; theslabs in one vertical plane being arranged also in horizontal coursesWith a slab of like character immediately opposite it in the othervertical plane; each slab being greater in legth than in depth With theopposite corners along one edge cut away and the respective ends thereofformed concave and covex but in reverse order; the slabs in alongitudinal coursebeing alternately reversed in position, vertically,and in abutting relationship along the longitudinal edges of theirprojecting end portions; and a plurality of bond blocks, superposed inalternating reversed position and in spaced vertical planes,transversely arranged intermediate the longitudinal slabs; saidbloclsrhaving a central section equivalent in Width to the spaceddistance between the vertical slab courses and With Wing portionsoutwardly projecting therefrom and arranged intermediate the adjacentends of the contiguous slab members and extending beyond said slabs; andconcave and convex faces on said blocks meinbering Withr the convex andconcave portions of said slabs, substantially as specified.
